R with Vim
For all those who think that Vim is The Editor for text files, and simultaneously think that R is The EnvironmentForStatisticalAnalysisAndGraphics. After trying out various options for intergrating Vim with R I settled on the following configuration: Use Vim-R-plugin for editing R code files, R documentation files (*.Rd) as well as the Sweave files.
